In the medical field, billions of dollars are wasted each year — about $935 billion, but who's counting? According to a paper published by the JAMA Network, an estimated $75.7 billion to $101.2 billion is wasted through overtreatment. Of the many procedures that can lead to wasted resources, breast cancer biopsies are a major source of overtreatment. Houston Methodist Hospital is using artificial intelligence to create a more efficient and accurate Breast Cancer Risk Calculator, called iBrisk.

Breast cancer is something that plagues the lives of many women, and some men. According to the National Breast Cancer Foundation, one in eight women will be diagnosed with breast cancer in their lifetime.

Women are advised to start having annual mammograms to screen for breast cancer starting at age 40 to try to catch cancer in its earliest stages. With mammograms becoming a standard procedure, the process inevitably leads to more biopsies.

While more biopsies sound like the obvious course of action, Houston Methodist Hospital shares that out of 10,000 women biopsied, less than two will be positive while using the national standard. The result of a negative biopsy? Wasted time, resources, and money, as well as undue worry for the patient.

"It's not just wasteful. . .when you do an unnecessary procedure, you're potentially harming the patient," says Stephen Wong, Ph.D. After a negative biopsy, Dr. Wong explains that patients often begin to show emotional responses like high anxiety and low self-esteem. They often speculate the biopsies are wrong, and that they've had a missed cancer diagnosis by their medical provider.

Dr. Wong estimates that more than 700,000 patients have unnecessary biopsies in the breast cancer category alone.

Spearheading the iBrisk tool, Dr. Wong has found a way to utilize a smarter model than the current system for detecting breast cancer risk.

Hospitals across the country currently use the Breast Imaging Reporting and Database System score (BI-RADS), a system created by the American College of Radiology to determine breast cancer risk and biopsy decision-making.

To expand on BI-RADS data, Dr. Wong used multiple patient data points and AI technology to create the improved system. The iBRISK integrates natural language processing, medical image analysis, and deep learning on multi-modal BI-RADS patient data to make one of three recommendations: biopsy not recommended, consider biopsy, or biopsy recommended.

"While using AI, we try to simulate how the physician thinks," explains Dr. Wong. "The physician looks at different data: imaging, patient clinical data, demographic, history and other social factors. You don't rely on one particular thing."

To create iBrisk, Dr. Wong used 12 to 13 years of BI-RAD data at Houston Methodist Hospital to train the AI using deep learning.

He estimates that more than 80 percent of technical information is in the free text format, meaning unstructured data, in the United States.

"We applied an AI technique called natural language processing, which is using the computer to read the text automatically for us," explains Dr. Wong.

This data extraction tool was also used with imaging of mammogram ultrasounds by applying image analysis computer vision.

iBrisk also deploys deep learning, a machine learning tactic where artificial neural networks, inspired by the human brain, learn from large amounts of data. They determined approximately 100 parameters to analyze, including age, sex, socio-economic data, medical history, and insurance plans. After putting the data points into a deep learning method, the AI reduced the data points to the 20 risk indicators.

Houston Methodist Hospital used an estimated 11,000 cases for training, and then used 2,200 of its own data to test iBrisk. They have even been able to create unbiased independent validation by working with other hospitals like MD Anderson, testing their patients using iBrisk and confirming the results.

The potential of iBrisk to cut costs and contribute to less overtreatment has garnered support with other hospitals around the country. The breast cancer risk calculator is a collaboration with Dr. Jenny Chang of HMCC and breast oncologists at MD Anderson, UT San Antonio, and University of Utah Cancer Center.

While implicit racial bias has become a more prominent issue in the United States, Houston Methodist's iBrisk grants a neutral, unbiased lens. AI isn't immune to racial bias; in fact, computer scientist and founder of the Algorithmic Justice League, Joy Buolamwini, uncovered the large gender and racial biases of AI systems sold by IBM, Amazon and Microsoft in a 2019 article for Time.

With AI's history of racial bias in mind, Dr. Wong set out to create an impartial, fair system. "Our AI data is not sensitive to race. . .it's unbiased," he explains.

Houston Methodist Hospital plans to expand the iBrisk model to other forms of cancer in the future, including its next venture into thyroid and incidental lung nodule screenings.

The AI allows patients to save the stress of getting a biopsy.

"We are very careful to put any drugs or any procedure into clinical workflow until we are very sure you really have to pick this [outcome]," explains Dr. Wong. Using advanced risk detectors like iBrisk allows medical practitioners to make more thorough, informed decisions for patients looking into biopsies.

The categories are broken into low, moderate and high-risk groups. The low-risk groups have seen a 99.8 percent accuracy in results, missing only two cases out of a sample of 1,228. Patients that have fallen into the high-risk groups (leading patients to get a biopsy) have seen an 85.9 percent accuracy, compared to radiology, which is 25 percent accurate according to Dr. Wong.

Dr. Wong notes that patients that fall in the moderate section of the risk assessment can then have a dialogue with their physician to determine if they want to move forward with the biopsy. In the moderate category, there is a 93.4 percent accuracy.

If implemented, iBrisk would be able to reduce 75 percent of unnecessary biopsies, estimates Dr. Wong.

Currently, Houston Methodist Hospital is using AI technology outside of oncology, with the recent release of a tool that can diagnose strokes using a smartphone, announced in Science Daily. The tool, which can diagnose abnormalities in a patient's speech and facial muscular movements, was made in collaboration with Dr. Jay Volpi of Eddy Scullock Stroke Center at Houston Methodist Hospital.

"We are answering bigger questions," explains Dr. Wong, who looks forward to continuing to expand AI capabilities and risk calculators at Houston Methodist Hospital.

In the future, Dr. Wong looks forward to doing a multicenter trial to bring this technology outside of Texas.

Texas cybersecurity co. expands unique train-to-hire model to Houston

job search

It’s increasingly more difficult to ensure the confidentiality, integrity, and availability of proprietary data and information in the ever-changing, ever-evolving digital world.

Cyberattacks, including malware, phishing, and ransomware, are becoming increasingly common and sophisticated, posing a consistent threat to a company’s sustainability and bottom line.

To combat that trend, Nukudo, a San Antonio-based cybersecurity workforce development company, is expanding its initiative to bridge the global cybersecurity talent gap through immersive training and job placement to Houston.

“We saw that there was a need in the market because there's a shortage of skilled manpower within the cybersecurity industry and other digital domains,” says Dean Gefen, CEO of NukuDo. “So, our initial goal was to take a large pool of people and then make them to be fully operational in cybersecurity in the shortest amount of time.”

The company refers to the plan as the “training-to-employment model,” which focuses on providing structured training to select individuals who then acquire the skills and knowledge necessary to secure and maintain fruitful careers.

The company identifies potential associates through its proprietary aptitude test, which recognizes individuals who possess the innate technical acumen and potential for success in various cybersecurity roles, regardless of their level of education.

“We take in people from all walks of life, meaning the program is purely based on the associate’s potential,” Gefen says. “We have people who were previously aircraft engineers, teachers, graphic designers, lawyers, insurance agents and so forth.”

Once selected, associates are trained by cybersecurity experts while gaining hands-on experience through scenario-based learning, enabling them to be deployed immediately as fully operational cybersecurity professionals.

The program training lasts just six months—all paid—followed by three years of guaranteed employment with NukuDo.

While in training, associates are paid $ 4,000 per month; then, they’re compensated by nearly double that amount over the next three years, ultimately pushing their salaries to well into the six figures after completing the entire commitment.

In addition to fostering a diverse talent pipeline in the cybersecurity field, NukuDo is creating a comprehensive solution to address the growing shortage of technical talent in the global workforce.

And arming people with new marketable skills has a litany of benefits, both professional and personal, Gefen says.

“Sometimes, we have associates who go on to make five times their previous salary,” says Gefen. “Add to that fact that we had someone that had a very difficult life beforehand and we were able to put him on a different path. That really hits home for us that we are making a difference.

Nulkudo currently has partnerships with companies such as Accenture Singapore and Singapore Airlines. Gefen says he and his team plans to have a new class of associates begin training every month by next year and take the model to the Texas Triangle (Houston, Austin and Dallas)—then possibly nationwide.

“The great thing about our program is that we train people above the level of possible threat of replacement by artificial intelligence,” Gefen says. “But what we are also doing, and this is due to requirements that we have received from clients that are already hiring our cyber professionals, is that we are now starting to deliver AI engineers and data scientists in other domains.”

“That means that we have added more programs to our cybersecurity program. So, we're also training people in data science and machine learning,” he continues.

All interested candidates for the program should be aware that a college degree is not required. NukuDo is genuinely interested in talented individuals, regardless of their background.

“The minimum that we are asking for is high school graduates,” Gefen says. “They don't need to have a college degree; they just need to have aptitude. And, of course, they need to be hungry to make this change.”

2 Houston universities declared among world’s best in 2026 rankings

Declaring the Best

Two Houston universities are in a class of their own, earning top spots on a new global ranking of the world's best universities.

Rice University and University of Houston are among the top 1,200 schools included in the QS World University Rankings 2026. Ten more schools across Texas make the list.

QS (Quacquarelli Symonds), a London-based provider of higher education data and analytics, compiles the prestigious list each year; the 2026 edition includes more than 1,500 universities from around the world. Factors used to rank the schools include academic reputation; employer reputation; faculty-student ratio; faculty research; and international research, students, and faculty.

In Texas, University of Texas at Austin lands at No. 1 in the state, No. 20 in the U.S., and No. 68 globally.

Houston's Rice University is close behind as Texas' No. 2 school. It ranks 29th in the U.S. and No. 119 in the world. Unlike UT, which fell two spots globally this year (from No. 66 to 68), Rice climbed up the charts, moving from 141st last year to No. 119.

University of Houston impresses as Texas' 4th highest-ranked school. It lands at No. 80 in the U.S. and No. 556 globally, also climbing about 100 spots up the chart.

Rice and UH are on a roll in regional, national, and international rankings this year.

Rice earned top-15 national rankings by both Niche.com and Forbes last fall. Rice claimed No. 1 and UH ranked No. 8 in Texas in U.S. News & World Report's 2025 rankings. Rice also topped WalletHub's 2025 list of the best colleges and universities in Texas for 2025.

More recently, in April, both UH and Rice made U.S. News' 2025 list of top grad schools.

In all, 192 U.S. universities made the 2026 QS World University Rankings — the most of any country. Topping the global list is the Massachusetts Institute of Technology (MIT).

“The results show that while U.S. higher education remains the global leader, its dominance is increasingly challenged by fast-rising emerging systems,” says the QS World University Rankings report. “A decade ago, 32 American universities [were] featured in the world’s top 100; today, that number has dropped to 26, and only 11 of these institutions have improved their position this year."

The 12 Texas universities that appear in the QS World University Rankings 2026 list are:

  • University of Texas at Austin, No. 20 in the U.S. and No. 68 in the world (down from No. 66 last year).
  • Rice University, No. 29 in the U.S. and No. 119 in the world (up from No. 141 last year).
  • Texas A&M University, No. 32 in the U.S. and No. 144 in the world (up from No. 154 last year).
  • University of Houston, No. 80 in the U.S. and No. 556 in the world (up from 651-660 last year).
  • University of Texas at Dallas, No. 85 in the U.S. and No. 597 in the world (down from 596 last year).
  • Texas Tech University, No. 104 in the U.S. and No. 731-740 in the world (unchanged from last year).
  • University of North Texas, No. 123 in the U.S. and No. 901-950 in the world (up from 1,001-1,200 last year)
  • Baylor University, tied for No. 136 in the U.S. and at No. 1,001-1,200 in the world (unchanged from last year).
  • Southern Methodist University, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas Arlington, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at San Antonio, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at El Paso, No. 172 in the U.S. and at 1,201-1,400 in the world (down from 1,001-1,200 last year).

Houston students develop new device to prepare astronauts for outer space

space race

Rice University students from the George R. Brown School of Engineering and Computing designed a space exercise harness that is comfortable, responsive, and adaptable and has the potential to assist with complex and demanding spacewalks.

A group of students—Emily Yao, Nikhil Ashri, Jose Noriega, Ben Bridges and graduate student Jack Kalicak—mentored by assistant professor of mechanical engineering Vanessa Sanchez, modernized harnesses that astronauts use to perform rigorous exercises. The harnesses are particularly important in preparing astronauts for a reduced-gravity space environment, where human muscles and bones atrophy faster than they do on Earth. However, traditional versions of the harnesses had many limitations that included chafing and bruising.

The new harnesses include sensors for astronauts to customize their workouts by using real-time data and feedback. An additional two sensors measure astronauts’ comfort and exercise performance based on temperature and humidity changes during exercise and load distribution at common pressure points.

“Our student-led team addressed this issue by adding pneumatic padding that offers a customized fit, distributes pressure over a large surface area to reduce discomfort or injuries and also seamlessly adapts to load shifts — all of which together improved astronauts’ performance,” Sanchez said in a news release. “It was very fulfilling to watch these young engineers work together to find innovative and tangible solutions to real-world problems … This innovative adjustable exercise harness transforms how astronauts exercise in space and will significantly improve their health and safety during spaceflights.”

The project was developed in response to a challenge posted by the HumanWorks Lab and Life Science Labs at NASA and NASA Johnson Space Center for the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge, where teams worked to solve problems for industry leaders.

Rice’s adaptive harness won the Best Challenge Response Award. It was funded by the National Science Foundation and Rice’s Office of Undergraduate Research and Inquiry.

“This challenge gave us the freedom to innovate and explore possibilities beyond the current harness technology,” Yao added in the release. “I’m especially proud of how our team worked together to build a working prototype that not only has real-world impact but also provides a foundation that NASA and space companies can build and iterate upon.”
